   <h2 class="title">简介</h2>
   <p class="para">
    BSON type for a 64-bit integer. This class cannot be instantiated and is
    only created during BSON decoding when a 64-bit integer cannot be
    represented as a PHP integer on a 32-bit platform. Versions of the driver
    before 1.5.0 would throw an exception when attempting to decode a 64-bit
    integer on a 32-bit platform.
   </p>
   <p class="para">
    During BSON encoding, objects of this class will convert back to a 64-bit
    integer type. This allows 64-bit integers to be roundtripped through a
    32-bit PHP environment without any loss of precision. The
    <a href="language.oop5.magic.html#object.tostring" class="link">__toString()</a> method allows the 64-bit
    integer value to be accessed as a string.
   </p>
   <blockquote class="note"><p><strong class="note">注意</strong>: 
    <span class="simpara">
     This class exists purely for 32-bit platforms. Applications on 64-bit
     platforms (i.e. <a href="reserved.constants.html#constant.php-int-size" class="link"><strong><code>PHP_INT_SIZE</code></strong></a> is 8) should never
     encounter this class during normal operation.
